Alstroemeria plant variety named `Stamial`

ABSTRACT

A new and distinct Alstroemeria plant variety producing flowers of good quality and attractive coloration.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of Alstroemeria originated as a seedling by crossing as seed parent an unreleased, unpatented seedling identified as 50B1200-01 and as pollen parent an unreleased, unpatented seedling identified as 50B300-01 from among my collection of Alstroemeria seedlings maintained under on controlled conditions in a greenhouse at Van Staaveren B.V., Aalsmeer, The Netherlands, for developmental purposes. The varietal denomination of the new variety is `Stamial`.

The first act of asexual reproduction of `Stamial` was in Aalsmer, The Netherlands, by propagation by dividing rootstocks. Asexual reproduction through successive generations has demonstrated that the combination of characteristics as herein disclosed for `Stamial` are firmly fixed and retained through successive generations of asexual reproduction.

`Stamial` has not been observed under all possible environmental conditions. Phenotypic expression may vary with variations in environment such as temperature, light intensity, day length and growing and cultural conditions.

SUMMARY OF THE INVENTION

Flowers of the new variety of Alstroemeria, `Stamial` are characterized by flowers of unusual coloration, as described herein. The plant blooms profusely with annual production, including production of flower stems in spring and fall under greenhouse conditions in The Netherlands, which is desirable characteristic in a cut flower variety. The flower-bearing stems are of excellent quality. `Stamial` grows productively under greenhouse conditions and is also reproducible both by division of rhizomes and by tissue culture.
